ABSTRACT:
A belt and pulley construction for use in a continuously variable power transmission arrangement. In one embodiment the conical working surfaces of the drive pulleys and the driven pulleys are comprised of removable segments formed of relatively erodable friction modifying material so that the conical pulley surfaces will wear away before the drive belt. In another embodiment the drive belt, whether comprised of a rubber compound or of metal, contains wear faces or pads which contain friction modifying material. Traction between the belt and the pulleys can thus be controlled by members other than solely through the tension of the drive belt.
